VPN Connection Successful but can only access devices by ip - Omada Software Controller
I'm able to connect my Iphone 12's vpn to the configured Client-To-Site VPN on the Omada Controller. I can access all devices but by ip only and so I cannot access my emails since it can't access my Exchange server.
I noticed when connecting to the vpn from a windows pc, the dns that is provided by the Omada vpn is 8.8.8.8 and I don't know where it gets that from since I don't have that configured anywhere in the controller. I have a local ip for dns in LAN which points to my DC which works just fine and when a device is connected it gets the DHCP's local ip and the configured DNS (192.168.2.252). On the pc I can force the dns to use my dns server but on an iphone I cannot change the dns server for the vpn.
How can I get the Omada Controller to issue vpn users 192.168.2.252 for dns instead of 8.8.8.8 when connecting via its vpn? On the vpn page we can only configure the IP Pool but not DNS. I guess it has 8.8.8.8 configured internally for this and cannot be changed?
